Latest Nuclear envelope Stories
The movement of genetic materials, such as RNA and ribosomes, from the nucleus to the cytoplasm is a critical component in a cell's ability to make the proteins necessary for essential biological functions.
Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells.
Researchers at MIT and Carnegie Mellon University are using both civil engineering and bioengineering approaches to study the behavior of a protein associated with progeria, a rare disorder in children that causes extremely rapid aging and usually ends in death from cardiovascular disease before age 16.
Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets.
Nuclear pores are the primary gatekeepers mediating communication between a cell's nucleus and its cytoplasm.
Nuclear pore complexes are best known as the communication channels that regulate the passage of all molecules to and from a cell's nucleus.
It turns out that wearing a cap is good for you, at least if you are a mammal cell.
Meiosis â€“ the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell â€“ is a major crossroads in all organisms reproducing sexually.
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell. Perhaps most notable is the double layered membrane that surrounds the nucleus, the cellular compartment which houses the cell's genetic material.
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.
